Of all things, why a Prius? Dean repeated to himself over and over again, his thoughts pained and foggy with betrayal. In the span of only a few hours, he'd lost the best companion he'd ever had, as well as his will to live. No matter how much cheap whiskey he drank, he couldn't drown the memories away.

The only one he'd ever truly loved, his midnight-black four-door 1967 Chevy Impala, had cheated on him.

πŸš— πŸš— πŸš—

No matter how hard he tried to unsee them, Dean couldn't forget the events of that night. He hadn't expected Baby to betray him, especially during his brief pit stop for a cheeseburger at Biggerson's, but he was mistaken; what he found in that parking lot shattered his heart.

Moonlight shone on the glistening hoods of two cars. They were parked side by side, engines purring. There was no mistaking it; it was her, and she had found a different partner for the road.

Dean had cried then, devastated. He wanted so badly to stop what was going on, to say something, anything at all. But all he could manage to choke out through the endless tears was "How could you?"

He wished for a second chance. He wished to relive the days past when he'd traveled highway after highway through day and night with her. But it was too late. She'd chosen a Prius over him. A Prius. Too much damage had been done.

"Baby, I loved you…" Dean began, but his voice trailed off. "I wanted a future together, roaming the open road, riding away into the sunset. But you-you chose a Prius over me?"

Dean waited for a reply, but Baby said nothing, as Baby is a car.

He bowed his head as tears poured down his face. He remembered his first midnight drive with the car he'd come to love. Ever since that fateful experience they both shared, she'd always been loyal, always made him feel so fulfilled. His best friend Castiel's words rang through his mind, maybe someday you'll fall for an angel. Cas was right; Baby was his angel, and he'd sell his soul just to forget the horrible sight of those two rear-view mirrors so close, the headlights dim.

Dean didn't ride in his beloved car that night. Once he couldn't bear to look at the awful scene before him any longer, he turned walked straight to the motel, not looking back, all the while feeling himself sink into unimaginable sadness. He had to accept the harsh reality: Baby didn't want him anymore. She only wanted the Prius.

πŸš— πŸš— πŸš—

Dean stepped out of his motel room and locked the door behind him, feeling hollow at the prospect of the empty life ahead of him. He was sick from a combination of depression and all the pie he'd eaten as comfort food, so he started off slowly, knowing he'd be suffering a lot through the long, difficult walk before him.

As he left, he noticed that Baby was not in the parking lot. And it was better that way–Dean didn't want her there. He was sure that if he saw her again, his now-fragile heart would just give out. He turned his attention to mapping out the path ahead. He wanted to be far, far away from here, and even further away from any Toyota dealership.

With a lonely sigh, Dean wandered off down the deserted road, walking away from Baby and the life he once knew.
